Cook the Israeli couscous according to package directions (I simmered mine for 17 minutes) then drain and rinse with cool water.
Meanwhile, prep the other ingredients.
Add all ingredients to a large bowl and toss together. Adjust vinegar and oil quantities as needed. Salad keeps well in the fridge for a couple of days.
Notes
If you're eating this as a main meal, it'll make about 2 portions.
